Does this mean that they have some sort of actuator that can move with nanometer precision? I didn’t realize that was possible… wow.

- GuB-42 5y agoThe best part is that you may already have one. Modern hard disks have a track pitch in tens of nanometers, and the read head has to move with matching precision, it also flies 3 nanometers above the surface.
- dwaltrip 5y agoWow, that's really cool. Thanks for sharing the knowledge. I didn't realize how physically precise modern hard drives were! I suppose if it makes sense if you think about how much information they are storing in a small space.
